She is expected to unveil a raft of measures to make it easier for local authorities to create more flats and houses in an attempt to shift the agenda away from Brexit to domestic issues.

However Mr Green, the First Secretary of State and de-facto deputy PM, told ITV it was “a more personal speech than you usually hear”.

He said “she will explain what drives her” to delegates as she tries to neutralise complaints about her robotic style - which has seen her dubbed the “May-bot”.

Damian Green said his boss will reveal 'what drives her'

The senior Cabinet figure told Good Morning Britain: "She will be explaining to people what drives her, what makes her so determined to fight for what she sees to be the right things for this country."

It comes after the week has been overshadowed by a damaging row with Boris Johnson, after the Foreign Secretary set out his own “red lines” for the Brexit negotiations.

But Mr Green added: “The vast majority of people I have spoken to, whether parliamentary colleagues or activists, are 100% behind the Prime Minister.

“The council house policy is part of measures to go to ‘those parts of society that often in the past’ the Conservative Party has not addressed.”

The renewed push on building new homes comes after the PM hired the former Tory housing minister Gavin Barwell to be her chief of staff.

It is a clear attempt to outflank Jeremy Corbyn on an issue which has been central to Labour's appeal to young voters.

She will also call on Tories to stop infighting and say it is time to "shape up" and focus on working for voters rather than obsessing about the leadership.

Against a backdrop bearing the slogan "Building a country that works for everyone", Mrs May will tell her party to "do our duty by Britain".

She will stress her own determination not to "give up" in the face of challenges and difficulties, as she calls on the party to "dig deep within ourselves" and go forward together.

Her acknowledgement that the Tories need to "shape up" may be seen as a response - conscious or not - to Mr Corbyn's challenge in Brighton last week for the Government to "pull yourselves together or make way" for Labour.

Have No10 been bingeing on box sets?

THERESA May’s aides were accused of lifting sections of her speech from US hit TV drama The West Wing – piling yet more misery on No.10.

Downing Street was forced to deny “plagiarism” after a series of extracts drew a striking resemblance to a keynote address by fictional President Josiah Bartlett, Steve Hawkes writes.

Speaking about resilience, the PM said that it was “when tested the most that we reach deep within ourselves and find our capacity to rise to the challenge”.

In the first episode of the fourth series of the West Wing, the fictional President remarks: “Every time we think e have measured our capacity to meet a challenge, we look up and we’re reminded that the capacity may well be limitless.”

Labour’s Jeremy Corbyn was hit by a plagiarism row in 2015 when it emerged his team had used a passage written years before by former political adviser Richard Heller.

Ex-Labour leader Neil Kinnock had a speech copied by US Democrat politician Joe Biden – before he became Barack Obama’s vice president. And last year, First Lady Melania Trump was accused of repeating huge chunks of a speech by Michelle Obama to the 2008 Democractic convention.

A No.10 spokesman said: “There is no question of plagiarism, but if you are interested in the PM's choice of US television shows, she is not interested in the West Wing.

"She prefers Friends."

Labour's deputy leader Tom Watson was among those to comment on the similarities yesterday. In a blog post he said: "It can be tempting to copy someone else's ideas and pass them off as your own.

"Theresa May seems to have done just that for her speech to Conservative Party Conference today, with a line from American TV drama The West Wing.

"It looks like she, or one of her speechwriters, is an Aaron Sorkin fan."

Maybe No10 should put down their boxsets...

The PM will focus on a renewed housebuilding strategy in her address to delegates

She is expected to tell activists: "Let us do our duty by Britain. Let us shape up and give the country the Government it needs.

"For beyond this hall, beyond the gossip pages of the newspapers, and beyond the streets, corridors and meeting rooms of Westminster, life continues - the daily lives of ordinary working people go on.

"And they must be our focus today.

"Not worrying about our job security, but theirs. Not addressing our concerns, but the issues, the problems, the challenges, that concern them.

"Not focusing on our future, but on the future of their children and their grandchildren - doing everything we can to ensure their tomorrow will be better than our today.

"That is what I am in politics for. To make a difference. To change things for the better. To hand on to the next generation a country that is stronger, fairer and more prosperous."
